Ive never had a bad trip with mushrooms... And it alll depends on what kind of sutuation your in while tripping. I've had a horrible trip on DXM, cuz i was caught while i was on it one time...(couldint respond when my dad was yelling at me) But it was my own fault, and i put myself in a risky situation.

So as long as your at peace with your emotions, and put yourself in a fool proof tripping enviroment, you should be good.
Also make sure you have alot of things you enjoy, whether it be your favorite munchies, music or games... make sure you have something you really like while tripping, it will help your good mindset, and you will have a blast.

Im glad ive never had a bad trip with mushies, they are too nice to me.
